BEER FILTER AND COOLER.

SPECIFICATION forming part of Letters Patent No. 681,841, dated September 3, 1901. Application filed December 5, 1900. Serial No. 38,790. (No model.)

To all whom it may concern.-

Be it known that I, LEROY A. WESTON, of Adams, in the county of Berkshire and State of Massachusetts, have invented a new and useful Improvement in Beer Filters and Coolers, of which the following is a specification.

My invention is in the nature of an improved beer filter and cooler which is designed to be built in the side wall of an icebox with only the dispensing faucet and valve projecting outside and with the body of the cooler containing thefilter projecting inside of the ice-box chamber to be cooled thereby; and it consists in the peculiar construction and arrangement of the parts, which I will now proceed to describe with reference to the accompanying drawings, in which- Figure 1 is a vertical section through the ice-box wall and my improved filter and cooler sustained thereon. Fig. 2 is a front view,- and Fig. 3 'an enlarged sectional View, of the valve.

A represents the side wall of the ice-box, to which is firmly attached the filter and cooler chamber B. This is made square in cross-section and projects at one end into the ice-box and is supported in this position by having its edges at one end flanged to form a shoulder and firmly seated in a square hole cut in the side wall of the ice-box. The hole that is cut in the outer casing of the side wall of the ice-box is a little larger than the hole in the inner casing, which latter fits snugly to the cross-sections of the body of the cooler-chamber. This forms a shoulder a, and on this shoulder is fastened by set-screws a cover-plate O, which tightly closes the said chamber. This construction and arrangement also braces and holds stifiiy the chamber B in its horizontal position. Between this cover and the outer face of the wall of the ice-box there is a space which is closed in by an ornamental outside cover-plate D. The bottom portion of the space between these two covers 0 and D is provided with a sheet-metal trough b to catch the drip of condensation, and this trough is I provided with an outlet vent-pipe c to carry away the drip.

In the bottom of the cooler there is tapped an inlet-pipe E for the beer as it comes from the keg, and this pipe has on its end a regulating-valve e, with an arm and ball e and also a horizontally-extended filtering-chamber F, constructed in the form of a cylinder or in other approved shape and construction so arranged that when the beer enters at pipe E it passes through valve e until the beer stands at a certain level in the cooler, at which it lifts the float-ball e and closes automatically the valve e', so that no more beer can enter, and yet when the level of the beer falls 'in this chamber as it is dispensed the lowering of the ball 6 will again open the valve e and admit more beer. The filter is to be made of fine-wire cloth with any suitablefiltering material, and the connecting end of the filter-cylinder is provided With a screwcoupling, so that it can be easily taken off and cleaned.

In the lower part of the cooler-chamber there is a dispensing-faucet G,wl1ich extends to the outside through the two front plates 0 and D, and from the top part of the cooler-chamber there extends through these front plates a valve H,which is designed to retain the pressure of gas in the cooling-chamber until it falls below a certain pressure and then it opens to allow air to pass in. This valve is mounted on the upturned end of a pipe 71. A cup h is attached to the pipe a little below its upper end and is screw threaded on theoutside, and a funnel-shaped casing h screw-threaded interiorly, is detachably screwed thereon with its spout end opening outwardly. Within the valve-chamber thus formed there is arranged a valve it, made of rubber or other light material and of a conical form, havinga stem projecting upwardly into the spout of the funnel-shaped case to hold it in central position, and this valve plays up and down between the end of the pipe h and the conical seat of the upper section of the case. The upper end of pipe It has notches in it that prevent the valve from ever closing the end of said pipe. The action of this valve is as follows: When beer passes into the cooler-case, the pressure of gas causes the valve h to rise and close the vent, so that no gas can escape; but when the faucet is opened and the gas pressure is relieved in the cooler from failure of valve 6 to'work the valve 72, drops down on the end of the pipe h and allows air to pass in through the notches in the upper end of the pipe, so that the beer will run freely out of thecooler.

In connection with the cooler I propose to use any suitable relief-valve which will blow off at any desired pressure.-

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. A beer cooler comprising a chamber fixed in the wall of an ice-box and projecting into the same, a cover-plate to the end of said chamber, a second cover-plate arranged outside the first on the exterior face of the ice-box,- and a drip-trough and vent-spout arranged at the bottom of the air-space between the two cover-plates substantially as ew-b e 2.; A beer cooler co" "prising an ic'e box having an inner and outer casing with holes through their sides opposite each other, the hole i n the inner casing being smaller than that in the outer one,'and a cooling-chamber secured in; horizontal position in said side walls and having its body portion made of a size to fit snugly the hole in the inner casing and having its o'u'ter end flanged to a larger size to fit the outer hole" and to form alsoa i shoulder to receive the closing-cover as described.

3. A combined beer cooler and filter comprising an inclosing-chamber having in its bottom a beer-inlet pipe with a filter and an "automatic float-valve arranged within the chamber, a dispensing-faucet arranged near the bottom of said chamber, and an automatic air-inlet valve arranged near the top substantially as and for the purpose de- -l scribed.

4.- A-combi-ned beer cooler and filter comprising an inclosing-chamber having in its l bottom a beer-inlet pipe with a filter and an automatic float -valve arranged within the chamber, a dispensing-faucet arranged near the bottom of said chamber, a pipe extend- ;ing from the top of the said chamber and turned up and notched, a; cup mounted on 3 the end of the pipe and screw-threaded exteriorly, an inverted funnel shaped case screwed onto said cup, and a conical valve iarranged within the same and playing bei tween the end of the pipe and the upper secition of the valve-case substantially as def scribed.
